Which prediction about a methane molecule would most likely be made by using both the quantum model of the atom and john dalton's model?

when the molecule reacts, new atoms are created.

the molecule contains different kinds of atoms.

the nucleus is located in the center of the molecule.

electrons are located at specific locations in the molecule.

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
